IMPROVEMENT IN SPPt'lNG-CATGHES FOR LAMPS.

Specification forming part of Letters Patent No. 39.33l, dated July "i,Ich?.

accompanying drawings, of which- `Figure 1 is a vertical section ot' alamp hprner witlrmy improvement. .Figa 2 isa front, and Eig 3 an edge,elevation, ot' -the spring-catch thereof.

. My invention or improvement restsin the "peculiar springcatch and itsapplication to or arrangement with the cup or deijector holdcr 'and thewicktnbc.

In the drawings, A is the defiect'or, supporter, or holder. while B isthe conical detiect- 'or and C the wickftnbe, of an ordinary burner ofa. lamp for the combustio n of kerosene or other hydrocarbon. Thespring-catch-f0r aiding in confining the delector and the glass chimneyin place within the' cap or holder A is vshown at D. 1t consists of athin strip' ofmetnl bent substantially in the form represented inFig. 3,in order that when in place in the lamp cap o r burner, its lower part,a, may rest directly against onel side of thelwiclctube, the part whichmay be alongside of the said tube being taperedor made thin, so as toact as a spring.

As shown in the drawings, the strip ot' metal 1 composing the catch Dhas four iiexures, b' o d e, and at a short distance below the second-'lexure, c, it is. furnished with 'two ears, ff,

extending from its two opposite edges, as

shown in Figs. 2 and 3.

the chimney in placein. the holder.

Inth'e application of thecatch to the lampcap or deflector-holder theupper part of the i catch, or that part of it which is above the two lears f f, is made to extend through a s lot'or hole, g, formed laterallythrough the rim' or the said holder, the two earsffbearingagainst' therim ad jacent to each end ofthe slot. Under these circumstances thelower portion of the catch, onthe part extending below the lower-'mostexure e, is to rest atits lower partdirect-ly against the adjacentside of the wicktube, which constitutes a bearing for it.- The lowerpart of the spring-catch is provided with one or two stops orshoulde1's,*h, to arrest the upward motion of the spring duringmediately adjacent to each end of the slot t',

through which the spring part ofthe .catch extends'. The tlexure b by'meansot' the spring will b 'e pressed down on the deiiector or thechimney when on the detlector, and will thus operate to keep the deectoror itB and person applying his thumb `to the upper part of thespring-catch and pressing it'back, the catch may be turned or moved soas to liber,- ate the chimney and deector, or the latter, ina manner toenable' such 'to `be readily re-l moved frein the holder.

yThe advantage of my springcatch is its simplicity in' make andapplication, it requiringno direct connection by, solder or otherwisewith the wick-tube or the cap, it beingheld in place by itsfexures andprojections.

I claimr The construction of the spring-catch audits application orarrangement relatively to the detlectonholder and the wiekftube, thewhole being substantially asabove specified.'
